I live in NE Ohio & have literally played the same two TruSoft balls for 18 to 54 holes the last 6 weekends in temps sometimes below freezing. I play throughout the winter here as long as there is not snow as 3 hours playing 18 holes with a few die hard partners even if cold is still playing. I have been impressed with the durability of the balls over this extended period in less than "typical" conditions but one of the two balls finally surrendered this morning on the first tee ball. I have been playing the TruSoft in the cold months the last 2 years and am genuinely impressed. While I play a different model of Titleist balls during warmer times, I am genuinely impressed by the durability and great feel that this model offers. Anyone looking for a great winter ball in similar climes who is used to playing ProV1s or X's during warm times should give serious consideration to the DT TruSoft. Another great example of Titleist products first in quality and performance.
